Robin Williams outside Ed Sullivan Theatre for the first live 'Late Show with David Letterman' since the Writers Guild of America strike began. New York City, USA - 02.01.08

The comedian-turned-actor has lined up 13 American dates in the run up to November's (08) election.

And he insists his own private life will be part of the joke, following his recent alcohol problems and his split from wife Marsha.

He says, "Between the politics and things that have happened to me personally, it's free range... It's an interesting time."
